Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 71,153,453, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 71,153,453 | |
| -1 | -71,153,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,153,453.
Example:
1 x 71,153,453 = 71,153,453
and
-1 x -71,153,453 = 71,153,453
Notice both answers equal 71,153,453
With that explanation out of the way, let's continue. Next, we take the number 71,153,453 and divide it by 2:
71,153,453 ÷ 2 = 35,576,726.5
If the quotient is a whole number, then 2 and 35,576,726.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 71,153,453 | |
| -1 | -71,153,453 |
Now, we try dividing 71,153,453 by 3:
71,153,453 ÷ 3 = 23,717,817.6667
If the quotient is a whole number, then 3 and 23,717,817.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 71,153,453 | |
| -1 | -71,153,453 |
Let's try dividing by 4:
71,153,453 ÷ 4 = 17,788,363.25
If the quotient is a whole number, then 4 and 17,788,363.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 71,153,453 | |
| -1 | 71,153,453 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 181 | 623 | 631 | 1,267 | 4,417 | 16,109 | 56,159 | 112,763 | 114,211 | 393,113 | 799,477 | 10,164,779 | 71,153,453 |
| -1 | -7 | -89 | -181 | -623 | -631 | -1,267 | -4,417 | -16,109 | -56,159 | -112,763 | -114,211 | -393,113 | -799,477 | -10,164,779 | -71,153,453 |
